I noticed that compiling footils/knob/knob.c and moonlib/mknob.c against Pd-0.41-test06 (HEAD of MAIN), I get a crash when using that object binary with Pd-0.40.3-extended-20071028.app and Pd-0.39.3- extended.app on Mac OS X. Is there some change in 0.41 that might cause this?

Here's the stack trace:
